Hi,

         I am getting following error  when I am running seldon-up command,  On Zookeepers 1 and 2 we get following error :

2018-03-13 12:11:32,217 [myid:3] - WARN  [QuorumPeer[myid=3]/0:0:0:0:0:0:0:0:2181:QuorumPeer$QuorumServer@155] - Failed to resolve address: zookeeper-1

Whereas on zookeeper3 we get following error:

2018-03-14 13:41:43,371 [myid:3] - INFO  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@192] - Accepted socket connection from /0:0:0:0:0:0:0:1:40024

DNS pods are running but still zookeepers are unable to identify each other. what's the issue? I have tries Calico, Weave Net and Flannel pod networks but still getting same error.

Thanks
